1 Claim. 1

The invention relates to improvements in dispensing devices and moreparticularly to the novel construction and association of partscomprising an easily mounted, inexpensive dispensing syphon.

The object of the invention is to provide a dispensing syphon of thecharacter referred to with novel means for attaching it to the neck of acontainer.

Another object of the invention is to provide a novel sleeve and ringstructure for mounting a dispensing syphon on the neck of a container.

Another object is to provide a dispensing syphon with novel valve means.

Another object is to provide a dispensing syphon with novel meansadapting it to be easily and quickly attached to and hermetically sealedover the pouring mouth of a container.

Other and further objects of the present invention will be apparent fromthe following description and claim, and are illustrated in theaccompanying drawing which, by way or illustration, shows an exemplaryembodiment and the principle thereof. Other embodiments of the inventionembodying the same principles may be used, and structural changes may bemade as desired by those skilled in the art without departing from thepresent invention and the purview of the appended claim.

In the drawing;

Figure 1 is a fragmentary sectional view of a container showing adispensing syphon, embodying features of the present invention, afiixedthereto.

Figure 2 is a fragmentary side elevational view of the dispensingsyphon, taken substantially along line 2-2 of Figure 1.

Figure 3 is a horizontal sectional detail view taken substantially alongline 3-45 of Figure 1.

Figure 4 is a vertical central sectional view of a dispensing syphonembodying modified features of construction, showing parts thereof inelevation.

The dispensing syphon embodying the features of the present inventionand illustrated in the accompanying drawing is of the character adaptedto be detachably secured over the pouring mouth of a container, such asa bottle. As shown, the container includes a neck H having an externallybeaded periphery surrounding its pouring mouth and provided, below saidbeaded periphery, with an external bead l2. The dispensing syphonpreferably is formed from sheet material suitably drawn into therequired con be understood, however, that it may be fabricated from anyother suitable material in any' other conventional manner.

The dispensing syphon consists, primarily, of

a pair of separable elements consisting of a cupshaped body is and asleeve Hi. The sleeve I4 is .1 cylindrical in shape and it includes aninternal flange i5 suitably formed on its lower edge. A pair ofdiametrically opposed bayonet slots 6- are provided in the cylindricalside wall thereof,:

each slot opening on the upper edge of the sleeve for purposes to beunderstood as the description- The inside diameter of the flange l5.

proceeds. is sufficiently large as to permit the sleeve to. be

r slipped loosely over the bead 12 of the neck Ii.

when the syphon is to be mounted thereon. The

flange i5 is adaptedto have seated thereon, a.

split retaining ring or collar ll which has an in- I ternal diameter ofsuch size as to snugly embrace. the neck of the container below the beadl2.

The body is is formed substantially cupshaped with its circular wall itdepending down-v wardly from the top Wall !9 thereof and is of suchdiameter as to have a free sliding fit within the circumferential sleeveit. A tubular stem 2!, formed axially on and extending upwardly.

from the wall is, is adapted to contain manually operable valve meansincluding an operating cap. 22. The cap 22 is, as illustrated,telescopically fitted over the open upper end of the tubular stem; 2|and it is provided with a depending rod 23, the lower end of whichcarries a valve element 24. The valve element 2% is arranged tocooperate with a circular valve seat provided on the lower end of asleeve 25 firmly secured within and depending from the lower end of thetubular stem 2!.

The valve normally is retained in closed position as by means of aspring 26 interposed between the cap 22 and an inwardly struckcircumferential bead'2'l formed in the tubular stem' 2!. A spout 28extends outwardly from and communicates with the tubular member 2!. Itshould be quite evident at this time that when the valve is closedcommunication between the interior of the container and the spout 28 isprevented. However, when the cap 22 is depressed manually, said valve ismoved into open position to thereby allow the container contents to flowupwardly through the sleeve 25, tubular stem 2i and out through thespout 28.

Movement of the container contents outwardly through the spout 28, whenthe valve is open, is

ngurations or from tubular material, It should 55 obtained by reason ofthe inherent pressure within the container. This pressure is present inall packaged carbonated beverages or the like.

Obviously, means must be provided in the dispensing syphon, or inassociation therewith, to prevent the escape of pressure from within thecontainer. Accordingly, the inverted cup-shaped body I3 is provided, onthe inside surface of its wall 19, with a circular Washer, or gasket,29, preferably fabricated from rubber or other suitable compressiblematerial of a kind not susceptible to rapid deterioration resulting fromcontact with the contents. The washer or annulus 29 has, formed integraltherewith, a downwardly extending tube 3| which terminates with its openend spaced above the bottom of the container.

The compressible washer 29 is adapted to afford an hermetic seal betweenthe inverted cupshaped top wall l9 and the end of the container neck. Itis, therefore, essential that said washer 29 be compressed when thedispensing syphon is mounted in place. Such compression of the washer 29is accomplished automatically upon mounting the body 13 on thecontainer. As best illustrated in Figure 2, the body l3 has a pair ofoutwardly projecting diametrically opposed pins 32, each of which isadapted to cooperate with one of the bayonet slots I6 in sleeve !4.Inasmuch as the portions of said slots 46 extending in a circumferentialdirection in the sleeve [4 are inclined downwardly slightly towardstheir terminal ends, engagement of the pins 32 therewith and subsequentrotation of the body [3 draws said body downwardly to compress thewasher 29. Such engagement and down drawing of the cup shaped body I3also tends to draw the sleeve 14 upwardly to thereby carry the splitring ll into close engagement with the container neck bead l2. In thismanner the container is hermetically sealed and inadvertent separationof the dispensing syphon from the container neck is prevented. It mightbe noted that the pins 32flextend outwardly of the sleeve l4 so as toafford finger engaging means when rotating the body.

Referring to the structure disclosed in Figure 4, the dispensing syphonbody I3 is substantially like that discussed hereinabove and is adoptedto cooperate with a retaining sleeve of the kind shown in Figure 1.Accordingly, like numbers will be used to identify corresponding parts.The Figure 4 structure differs, however, from that previously describedin the construction of the valve embodied therein.

As shown, the valve includes the depressible cap 22 and rod 26. In thisinstance, however, the lower end of the rod 26 carries a plunger 33which has a slide fit in a valve element 34. The valve element 34 is inthe form of a nipple firmly secured at its upper end in the lower end ofthe tubular portion 2! and of such length that the plunger 33 remainswithin its end limits irrespective of whether or not the valve plungeris elevated or depressed. When in the elevated position illustrated, theplunger 33 effectively stops the flow of fluid from the interior of thecontainer to the spout 28. However, upon depression of the cap 22, theplunger 33 is carried into a position below radial ports 35 provided inthe wall of the nipple 34. The fluid contents of the container uponwhich the dispensing syphon is mounted is then free to flow through theports 35 and out of the spout.

Although exemplary forms of the invention have been disclosed in theaccompanying drawing and described in detail in the foregoingspecification it should be understood that the invention is capable ofembodying a wide variety of modifications in detail construction withoutdeparting from the spirit of the invention or the scope of the appendedclaim.

I claim:

A dispensing syphon adapted to be fitted over the pouring neck of anexternally beaded container comprising a sleeve adapted to be fittedover said beaded. neck, asplit ring insert in said sleeve adapted toengage beneath the bead to prevent withdrawal of the sleeve, an invertedcupshaped body fitted over the neck and into the sleeve, meansdetachably connecting the body and sleeve, a gasket within the bodyadapted to overlie the pouring opening when the body and sleeve aresecured together, said gasket having a tubular portion dependingtherefrom into the container and open at its lower end, a tubular stemintegral with and communicating with the interior of said body andextending outwardly from the body end wall, a spout on and communicatingwith the interior of the stem, a sleeve in the body anchored at one endin the stem and having a valve seat at its other end which projects intothe body, and a valve element cooperating with the seat, said valveelement being movable to permit the contents of the container to bewithdrawn through the tubular portion and dispensed through the spout.
